Filed: 1926-04-19
Abstract: 250,976. British Thomson-Houston Co., Ltd., (Assignees of Goff, R. W.). April 18, 1925, [Convention date]. Controllers.-Relates to electromagnetically operated change-over switches such as are employed in star-delta starters for motors. The operating magnet 11 attracts an armature 12 linked to a pivoted bar 19 attached to a cam 22, which by reaction on a pin 23 moves an arm 14 from the position of Fig. 2 to that of Fig. 3. The arm 14 being rigidly fixed to a shaft 13, motion is imparted to a group of switch contacts 39, thus, in the case of a motor-starter, bringing about the starting position. A simultaneous movement is imparted to an arm 18 loosely mounted on the shaft 13, the effect of which is to strain a spring 24 tending to carry the arm 14, and with it the contacts 39, from the starting to the running position. The actual change over takes place after the magnet 11 has been momentarily de-energized and again energized, for which purpose use may be made of a delayed action relay 26 of the kind described in Specification 215,384. Diagrams of a push-button controlled star-delta starter are given in the Specification.

[Class 29] Absorption systems.-Solid absorbents for reversing systems, especially substances which swell up during absorption of the refrigerant, are prepared ready for charging into the generator-absorber vessels by treatment in an evacuated vessel to which a measured quantity of refrigerant is introduced in the liquid state, the heat of absorption serving to promote evaporation of the refrigerant and thereby hastening the period of complete absorption. As shown in Fig. 2, the absorbent may be placed in boxes 2 in a vessel 1 having a connection to a vacuum pump 3, and liquid refrigerant is supplied from a bottle 4, supported by a weighing machine 9, through a valved pipe 5 and a pipe 7 reaching to the bottom of the vessel 1. Each box may contain the charge for one generator-absorber,and if equal sized boxes are employed for different sizes of generatorabsorbers, the boxes with the smaller charges of absorbent are placed in the upper tier. The material may be subjected to movement during treatment. In the arrangement shown in Fig. 3, the evacuated vessel 31 is adapted for rotation by a motor 34. The absorbent is placed in one compartment 41 and the refrigerant in another compartment 45 separated by a partition 43 with a central aperture 42. In another arrangement the absorbent may be placed in a series of drum-like vessels having openings for access of refrigerant vapour in their vertical walls, and mounted in a rotary evacuated vessel charged with the required amount of refrigerant.

Title: Improvements in or relating to Telephone or like Systems

Filed: 1967-03-03
Abstract: 1,157,153. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. 23 Feb., 1968 [3 March, 1967], No. 10285/67. Heading H4K. A trunk circuit Tc, accessible to a reed relay group selector and a Strowger group selector SS, is deemed unavailable by the reed relay group selector both when there is busy earth on the C-wire and when the C-wire carries negative voltage over the low resistance of the H relay of a forwardly testing Strowger switch. To discriminate these conditions in the interrogator/marker of the reed relay group selector the C-wires of a 20 line group are connected over contacts TS1 to TS20 to individual interrogators such as I1 employing transistors T1 to T5. If the interrogator finds busy earth on the C-wire the Zener diodes Z1, Z2 prevent cut-off of a normally conducting transistor T1, transistors T2 and T3 being and remaining cut-off. Normally conducting transistor T5 in consequence stays conductive and by holding earth on lead SL1 signals that the trunk is unavailable. If the interrogator finds 50 volts negative over the low resistance of a relay H in a Strowger switch, voltages of about 50 and 37 volts negative appear at the points L and M of the interrogator. The Zener diodes Z1, Z2 with trigger voltages of about 15 volts each consequently break down to cut-off T1 which switches on T2. The voltage at M switches T3 on but with T2 conducting diode D3 is back biased and T5 remains conducting to signal that the trunk is unavailable with earth on SL1. If the interrogator finds 50 volts negative over resistor R1 on the C-wire (trunk circuit idle), a voltage of about 27 volts negative appears at point L this being insufficient to cut-off T1 over the Zener diodes but causing T3 to switch on to cut-off T5, the consequent removal of earth from SL signalling that the trunk circuit is available. The free condition of the trunk is not signalled over lead SL1 if the associated primary/secondary link of the reed relay group selector is not available. Should the associated link be busy a transistor T4 is held conductive and backs off diode D3 to prevent the idle condition of the trunk reaching T5 to switch it off. Capacitance of the C-wire, since it needs time to charge after the removal of busying earth, may delay the interrogator in signalling the free condition of the trunk. A delayed response is also produced when the capacitance of the C-wire is fully charged to 50 volts negative over R1, the initial discharge of the C-wire into the interrogator causing it to respond as if the C-wire were subject to test from a Strowger selector.

Title: Improvements in or relating to the synthesis of hydrocarbons and catalysts therefor
IPC: B01J37/26
Filed: 1947-04-18
Abstract: Iron containing catalysts for the Fischer-Tropsch synthesis are prepared by incorporating a fluoborate into iron oxide, iron hydroxide or an iron ore in the range 0.2 to 10 per cent by weight of the iron and then reducing at least part of the iron compound to the metallic state.  The reduction is effected between 500 DEG  and 1600 DEG  F. and the preferred fluoborate is potassium fluoborate. Mixtures of fluoborates may be used as promoters.  The catalysts may be used in fixed bed, moving bed or fluidized type of operation.ALSO:The synthesis of hydrocarbons and oxygenated hydrocarbons from mixtures of carbon monoxide and hydrogen and the polymerization of olefines, whereby gaseous olefines are converted into olefines boiling in the gasoline boiling range, are carried out with the aid of a catalyst consisting essentially of a reduced form of iron oxide, iron hydroxide or iron oxide ore having incorporated therein a fluoborate, in particular 0.2 to 10 per cent by weight thereof based on the iron content of the catalyst.  Sodium, potassium, calcium and caesium fluoborates are mentioned.  The hydrocarbon synthesis is effected under the usual conditions of temperature and pressure, the catalyst being used in fixed or moving bed operation or preferably in the fluidized state.  In an example, carbon monoxide and hydrogen are passed at elevated temperature and pressure through a bed of catalyst prepared by pasting iron oxide with potassium fluoborate and reducing with hydrogen at 900 DEG  F. (see Group III), there being obtained propane, propylene, C4 + liquid hydrocarbons (mainly unsaturated), alcohols and acids (ethyl alcohol and acetic acid) and a wax.  Comparative experiments employ, as catalyst promoters, potassium fluoride and potassium carbonate in place of the fluoborate.
